Once I was in a crystal shop, I accidentally broke several crystal wineglasses. At first, I was very worried and was fraid to need to compensate them because they were so expensive. However, the shop staff told me that since it is the shop's decision to put the merchandise in the aisle, the shop should bear the full responsibility that customers may break the glasses(merchandise) by accident. Therefore, I need to compensate nothing for my carelessness.
However, I felt so sorry for what I had done. So, I bought many crystal glasses and fruit plates from that shop that day.
Good merchants always know what is good for them to do. --- That's what I learned from my own experience.
